Trades (excluding aid and tribute) come in two froms: one way or two way. A one way trade is somebody needs something you've got, so you can name your price. Two way is a mutually advantageous trades, like finding a bunch of death gems and trading them for a horror helm from Ermor when you have no death mages.

Aid is something different, its when you basically give something away to help another player out. A classic example is giving anti-undead equipment to a player going up against Ermor so you don't have to.

Obviously, tribute is a demand for resources in exchange for not anihilating a player.

As for individual items, here's my list of items worth trading for if you can't get them naturally:

-Any gems that you don't have an income for, but do have mages capable of casting the site searching spell for.

-Fire Brand and Frost Brand

-Horror Helm

-Various elemental immunity rings

-Amulet of Resiliance, Messenger Boot, and Girdle of Might

-Rune Smasher

-Luck Amulet or other Luck items

-Boots of Quickness

-Magic Path boosters and will let you build the boosters

OK, most of those items are for thug and SC chasises, I guess that tells you where my playstyle is at right now.
